Topology and API

This is a nested lingtai-portal-guide reference. It covers the on-disk topology tape, replay chunks, HTTP endpoints, and live network JSON shape.

topology.jsonl

Each line is a TapeFrame:

{
  "t": 1744567890123,
  "net": { "nodes": [...], "avatar_edges": [...], "contact_edges": [...], "mail_edges": [...], "stats": {...} }
}

t is milliseconds since epoch. net is the same Network object /api/network serves; Network response shape below is a representative example of its core fields.

Replay chunks

Historical data is stored as delta-encoded, keyframed, gzipped JSON chunks bucketed by hour under .lingtai/.portal/replay/chunks/. The manifest.json in that chunks directory lists all available chunks with their time ranges and frame counts.

API endpoints

All endpoints are served at http://localhost:<port>.

Endpoint	Method	Response	Description
/api/network	GET	Network JSON	Live network state (nodes, edges, stats)
/api/topology	GET	JSON array of TapeFrame	Full topology tape (can be large)
/api/topology/manifest	GET	ReplayManifest JSON	Chunk metadata for replay
/api/topology/chunk?start=<hourMs>	GET	Chunk JSON (optionally gzip-encoded when requested)	Frames for one hour-bucket start time
/api/topology/progress	GET	JSON object such as { "current": N, "total": M } (or {})	Reconstruction progress parsed from reconstruct.progress
/api/topology/rebuild	POST	ReplayManifest JSON	Trigger tape reconstruction from source data and rewrite replay chunks
